This is my second attempt at a plyo box. This time in technicolor! I took a ShopBot class at TechShop and decided it would work better than the inaccuracies of the table saw and band saw.


3/4" sheet of plywood (I chose a birch variety)

Two-flute end mill (I chose 1/4")


Screws (at least 1.5 in long)



End Mill

Drill bit (1/8")

Brass screws (long enough to go through material; 1.5")

Step 1: Creation of the Plans

I detailed in my other instructable that I modified a few plans to get to one I liked. I mocked up the same plans in Illustrator which is the one of the pictures in this step. I was able to include the drill holes here as well. I planned on using the edges to my advantage to minimize cuts, this wasn't the best choice and I will tell you why later in the next step.

Here is the file that I put together with Adobe Illustrator. It is in a public file from dropbox.


<p>If you use a 3/4 in veneer and a few 1x2's or 2x2's it should be more than enough. Just frame the inside and a brace in the middle of each piece. You can actual use this for three different heights if you reinforce it right. </p>
I really feel it is strong enough without any bracing inside already. Certainly it's strong enough in the narrow directions, and the widest (24&quot; tall) which is what use the most, I feel comfortable without any bracing. Of course, better safe than sorry.
<p>Thanks for the directions, is the <a href="http://topplyometricboxes.com" rel="nofollow">plyo box</a> strong enough on it's own for someone 220lbs? Or should it be reinforced with 2x4s?</p>
I wouldn't be able to give you an answer confidently since I am not 220lbs or an engineer. While the box feels sturdy to me, the boxes that get sold by gyms and equipment manufacturers almost always have a center piece internally for reinforcement.
